Question about suspension

If you are swapping K frames, only 63-66 will interchange. Drag links come in 2 varieties for the early A - slant and V8. Upper control arms are identical 63-72 and use the small ball joint. 73-76 also fit and come mostly with the large ball joint although i have seen some slant 73-76s come with the small ball joint. 63-76 lower control arms are all the same with the exception of the sway bar tabs (if equipped with a sway bar). Sway bar families are 65/66, 66-72 and 73-76. Hope thus helos
